Replying to [comment:5 kainz]:
> So on a pi0w using a similar setup, but with a PCM line mic that i've
got rigged to show up as a alsa PCM capture device @48000/s16le, I can
absolutely reproduce the CPU usage issue when running `ffmpeg -f alsa -i
default -acodec pcm_s16le out.wav`
Please confirm that the issue is not reproducible with `arecord`.
